rFhis. invention relates-` to surf boards. cf `thereinforced sufficiently to prevent buckling when a'v force is. applied. atanypoint thereon.

The .usuali surf. board-is comparatively thinand of: light weight.. construction and' when double walls aref. used. the thin. material: thereof hasa tendency4 tobucklewhen the loadis concentrated at; one point. With. thisthoughtfin mind this inv vention contemplates a continuous innerv reinforcing forfsurf boards.. of the. hollow type-with the. said.. reinforcing member.- corrugated longitudinally and transversely wherein the walls are supported at a plurality of points so that they are adapted to resist compression forces from the deck.

The object of this invention is to provide means board internally without sacrificing the buoyancy thereof.

Another object of the invention is to provide means for reinforcing a surf board by incorporating elements within the hull of the board which prevents twisting, bending, or buckling at substantially all points.

A further object of the surf board that throughout its length and width, which is of a simple and economical construction.

With these and other objects and advantages in view the invention consists of the new and novel combination, construction, and arrangement of parts as hereinafter more fully described, set forth in the claims appended hereto, and disclosed in the accompanying drawings, forming part hereof, wherein:

Figure 1L is; acrossesection.throughithe surii board shownin. Figura-10.

Referring nom to.- the'. drawings: whereinllikev reference characters indicate corresponding parts the surf board of this invention is formed with a deck I0, a bottom II, sides I2 and i3, a skeleton or inner frame I4, and a rubber mat I5 providing a deck covering.

The deck I0, as shown in Figures 1 and 5 is formed with longitudinally positioned ribs or corrugations I6 which provide reinforcing, and, as shown in Figure 5, the ribs extend upward through slots I'I in the mat I5.

The bottom and sides are substantially flat with arcuate ends, and the edges are joined by rubber bonds or beads I3 which are formed with slo-ts IS and 20 that receive the edges of the sheets of material as shown in Figure 5.

The edges of the sides, bottom, and deck may also be welded as shown in Figure 7 in which a side 2| is welded to a bottom 22 with welding beads 23 and 24 formed thereon.

The inner frame I4 is formed with relatively large corrugations 25, as shown in Figure 3, which extend transversely across the surf board and the surfaces thereof are formed With longitudinally disposed corrugations 26, as shown in Figure 5.

The inner frame I4 is connected to the deck and bottom through the high or low points of the corrugations by rivets 21, as shown in Figure 4, however it will be understood that the parts may be connected or attached by any suitable means.

In the design illustrated in Figures 10 and 11 the surf board is similar except that the deck is provided with transverse corrugations 28, and the inner frame may also be connected to the parts by rivets or welding as desired.

With the parts arranged in this manner, and particularly with the parts made of aluminum, a buoyant, stable, and fast surf board will be provdied, and all external forces or internal stresses will be absorbed by the inner frame.

It will be understood that other modifications may be made in the design and arrangement of the parts Without departing from the spirit of the invention.

What is claimed is:

1. A surf board comprising a substantially hollow hull fomed of bottom, side, and deck plates with the deck spaced from the bottom, and an inner corrugated reinforcing frame extending continuously from end to end of the hull retaining the plates in spaced relation continuously throughout the length thereof.

2. A surf board comprising a substantially hollow hull having bottom, side, and deck plates with the deck spaced from the bottom, and an inner corrugated reinforcing frame extending continuously from end to end of the hull with the high and low points of the corrugations in engagement with the deck and bottom respectively.

3. A surf board comprising a substantially hollow hull having bottom, side and deck plates with the deck plate spaced from the bottom plate, an inner reinforcing frame corrugated longitudinally and transversely positioned in the hull retaining the deck and bottom plates in spaced relation, and means connecting the high and low 4 points of the corrugations to the deck and bottom plates respectively.

4. A surf board comprising a substantially hollow full formed of bottom, side, and deck plates of lightweight metal, the adjoining edges of the plates being sealed in air and watertight relation, and stifening means for the hull comprising an inner corrugated reinforcing frame extending continuously from end to end of the hull retaining the plates in spacedrelation and contacting the plates at spaced points continuously throughout the length thereof 5. A surf board comprising a substantially hollow hull having arcuate sides with converging ends formed of bottom, side and deck sheets of lightweight material, the adjoining edges of the sheets being joined in air and watertight relation, a rubber mat covering the deck, said deck having corrugations therein, and stiiening means for the hull includingaI corrugated sheet extending continuously throughout the hull and supporting the deck and bottom sheets at spaced points continuously throughout the length thereof.
